Hey, I'm Adrian. I did the 'More colors' shader.
Given the nature of the project, a hackathon, sticking to the last computed FFTs and a notion of time was all we need to play with nice shader effects.
I'm currently playing with tensorflow on my spare time. I'd like to use a neural net to find interesting features of a track and inputting this to a shader. That's what I would do if I had another go at it.
